I'd just like to add I'm a new Linx 8 user (bought it 2 days ago) and am absolutely loving it so far. After an initial full charge I installed all updates etc, then charged it overnight and took it off charge at around 8am. I then left it asleep (rather than turned off) and when I next turned it on at around 12pm it was down to 81% battery. So I had around 5% battery loss per hour when asleep. Nothing running, bluetooth off, no SD card in, completely stock install apart from all available updates installed.
I switched to the drivers posted above:

(copied the files to the Linx, went to device manager, selected the realteck wifi adaptor, right-click -> update driver, selected the folder where the drivers were, update).
It picked up the new driver and installed it fine. I then rebooted the Linx (power button pressed until sliding power off option appears, power off, then power button again to restart).
I then put it to sleep again and awoke it over 2 hours later. I saw 1% battery loss, so around 0.5% per hour. As posted elsewhere a 10x improvement.
I will keep monitoring but looks good so far
